[renderer] Support multiple entity queues While there's currently only the one still, this will allow the entities to be multiply queued for multi-pass rendering (eg, shadows). As the avoidance of putting an entity in the same queue more than once relies on the entity id, all entities now come from the scene (which is stored in cl_world in the client code for nq and qw), thus the extensive changes in the clients.

[scene] Move entity_t etc into scene headers I meant to do this a while ago but forgot about it. Things are a bit of a mess in that the renderer knows too much about entities, but eventually the renderer will know about only things to render (meshes, particles, etc).

[model] Move plane info into mnode_t, and visframe out The main goal was to get visframe out of mnode_t to make it thread-safe (each thread can have its own visframe array), but moving the plane info into mnode_t made for better data access patters when traversing the bsp tree as the plane is right there with the child indices. Nicely, the size of mnode_t is the same as before (64 bytes due to alignment), with 4 bytes wasted. Performance-wise, there seems to be very little difference. Maybe slightly slower. The unfortunate thing about the change is the plane distance is negated, possibly leading to some confusion, particularly since the box and sphere culling functions were affected. However, this is so point-plane distance calculations can be done with a single 4d dot product.

[vulkan] Use a buffer for entity transform and color data This allows the use of an entity id to index into the entity data and fetch the transform and colormod data in the vertex shader, thus making instanced rendering possible. Non-world brush entities are still not rendered, but the world entity is using both the entity data buffer and entid buffer.

[scene] Swtich from - to ~ for entity id index It saves only 1 bit in the set, but it could save on allocations. Also takes care of a FIXME :P
